Single Mobile Micro Droplet-Particle Pairs Spatially Captured by Macro Host Droplets on a Superhydrophobic Surface

Figure 3

Self-propulsion of condensed secondary water droplets from the host drop. (a) Two particle-secondary droplet pairs in close proximity. (b) Less than 1 ms after the two secondary droplets have merged and self-propelled off the two surface bound particles. The particles remain on the surface of the host drop (see also Movie S5).
